I had a standard tabular lock in my front door. Recently, it start functioning differently than before and I wonder if the lock is broken or there is a different reason for it. In the past, whenever leaving the house, we would switch the internal clip and go out and shut the door which should keep it locked. Recently, Whenever we tried to "shut the door", the latch is static not allowing us to shut the door. The only way now is to use the key.
Your advice is much appreciated.
David.
